That's kind of my point: The tech community can relate to Doom in the context of their own childhoods because we grew up with it. Adults can't relate to Instagram in the context of childhoods because that came after our time. So without first-hand experience, they substitute whatever feels correct, as prompted by hyperbolic articles like this one.
Every generation thinks the way they grew up was correct, while subsequent social changes are bad. There has always been moral panic about what "kids these days" are doing, from social media to video games to portable music players to watching TV and so on.
It was the exact same story with video game violence: Adults at the time didn't grow up with video games, so they assumed the worst. Politicians and news media stepped in to seed the most dramatic possible interpretations, pointing to correlations with increasing gun violence (at the time). To adults who didn't grow up with the context and saw no personal upside to the video games, heavy-handed legislation felt right.
